Re: 240/230/220V
It didn't. They changed the % limits for Mainland Europe, GB, NI and Ireland. It's mostly 240V in UK, 220V in Germany and 230V in Ireland, like it always was. Equipment marked CE has to work in any EU electrical supply, though it MUST have the local standard of plug, if it plugs in.
The most criminal is Amazon supplying 5V chargers with a CE mark. Yet they only have the USA two blades, illegal in all of Europe to retail. The actual electronics like most SMPSU do seem to work 90V to 245V.
Older 220V gear with a transformer and no taps (Such as German Market radios) may need a dropper resistor in the UK.
